Fraction Multiplication Formula:
From: | To: |
Fraction multiplication involves multiplying the numerators together and the denominators together. The product of two fractions is a new fraction where the numerator is the product of the original numerators and the denominator is the product of the original denominators.
The calculator uses the fraction multiplication formula:
Where:
Explanation: The calculator multiplies the numerators (a × c) and denominators (b × d) separately, then simplifies the resulting fraction by dividing both numerator and denominator by their greatest common divisor.
Details: Fraction multiplication is fundamental in mathematics, used in scaling recipes, calculating probabilities, determining areas, and solving many real-world problems involving ratios and proportions.
Tips: Enter all four values (two numerators and two denominators). Denominators cannot be zero. The calculator will show both the fractional result (simplified if possible) and the decimal equivalent.
Q1: Can I multiply fractions with different denominators?
A: Yes! Unlike addition, fraction multiplication doesn't require common denominators. You simply multiply numerators and denominators directly.
Q2: What if one denominator is zero?
A: Division by zero is undefined. The calculator requires all denominators to be non-zero numbers.
Q3: Does the order of multiplication matter?
A: No, fraction multiplication is commutative: a/b × c/d = c/d × a/b.
Q4: How does the calculator simplify fractions?
A: It finds the greatest common divisor (GCD) of the numerator and denominator, then divides both by this number.
Q5: Can I enter mixed numbers?
A: This calculator requires proper or improper fractions. Convert mixed numbers to improper fractions first (e.g., 1½ becomes 3/2).
